The Effects of CoRe-based Science Lesson on the Scientific Conceptual Formation and Academic Achievement of Elementary School Students

This study aimed to investigate the changes in learner's scientific conceptual formation and academic achievement after a CoRe-based science lesson. For this study, two classes of the 6th grade of elementary school were divided into an experimental class and a comparison one. The students of the experimental class received CoRe-based science lesson and those of the comparison one received general science lesson. Both of the classes studied 'unit 1. A change in the weather', which is a part of content of 6th grade science text book. The results of this study were as follows. First, in the questions of invisible and abstract phenomena, students had misconceptions based on their experience in real life, or did not understand the fundamental causes of that phenomena. But after receiving lessons respectively, experimental class generally showed at a higher rate of understanding the causes of the phenomena than comparison class. Second, CoRe-based science lesson was more effective to improve students' scientific conceptual formation than the general science lesson. Moreover, when two classes were respectively divided into two groups as high and low-level groups according to their pre-test achievement records, the CoRe-based science lesson was more effective to learners of the high-level groups. Third, CoRe-based science lesson was more effective to enhance students' academic achievements than the general science lesson, especially to learners of the low-level groups.
